The Binary Titanium Carabiner is a revolutionary design of a carabiner with the safety gate for the keys and the built-in bottle opener. By using an extreme nesting structure, the team is trying to create a design with lower material costs on titanium. All binary carabiners use the similar nesting structure and were designed using mirror images along multiple axis to fit this puzzle together. There are two finishes you can choose from – bead blasted and polished. Since the binary carabiner is a pretty small design, it’s often difficult to use fingers for a leverage when opening the bottle. For the small version of the binary carabiners, you can pull on the key ring to open the bottle, but you need to stop it from sliding into the gate and lose the leverage you need. Hence the hook which holds the key ring has been placed at an optimum position. A perfect everyday carry you shouldn’t miss having in your pockets!
